MACHINE FOR CUTTING AND MITERING PRINTERS RULES.

SPECIFICATION forming part of Letters Patent No. 413,522, dated October22, 1889.

Application filed May 14, 18-89. Serial No. 310,709. (No model.)

To all whom t may concern,.-

Be it known that we, WILLIAM A. KELSEY and RICHARD ATWATER, of Meriden,in the county of New Haven and State of Connecticut, have invented newand useful- Improvements in Cutting and Mitering Machines for PrintersRules; and we do hereby declare the following to be a full, clear, andexact description of said' invention, reference being had to theaccompanying drawings, and to the letters or igures of reference markedthereon, which form a part of this specification.

Onr invention relates to improvements in machines for cutting andmitering printers rules in which a lever-blade is employed to performthe operation of mitering or bevelin g the end ofa rule as well as thecutting of rules to given lengths; and our object is to produce a simpleand economical machine capable of performing the two operations easilyand quickly.

Our invention consists in the construction and combination of parts, ashereinafter described, and pointed out in the claims.

In the drawings which accompany and form a part of this specification,Figure l is a perspective view of the machine complete. Fig. 2 is a planview of the same. Fig. 3 is a side elevation looking from the directionof the arrow in Fig. 2, and Fig. A is a Acrosssection of the lever bladeor knife on line .es of Fig. 3.

Similar letters of reference indicate corre spending parts in theseveral views.

The base X,'having suitable means for securing it to a bench or table orwhich may be of sufficient weight to require no fastening, is formedwith a straight portion having the rule-bed w, and with a quadrantshapedportion m', having an are slot Q02 and a hole or recess ac3 at thecenter of the arc. At the corner of the base where the straight side ofthe arc-bed meets the farther side of the rule-bed a bearing x4 isformed for the pivot-pin or fulcrum F of the lever-blade A. Thisleverblade, having the handle a, has two cutting edges o. and a2, theformer when the lever is down being opposite the end of the rulebed andthe latter being opposite the point of the arc-bed where the recess x5is located.

Both of these cuttingfedges are parallel with the length or longitudinalaxis of the lever A, thereby causing a shear cut to be made. At theportion of the lever-blade where the cut ting-edge a2 is located is alug B. This lug, as shown, projects from the outer side of the leverdown and under said lever to a point nearly under the edge a2. lug isbeveled from its lowest point upward, and is for a purpose hereinafterexplained.

The swinging gage C of the arc-bed has at one end adownwardly-projecting pin c to enter the hole or recess :r3 in the bed,and which serves as the center of motion for Athe-said gage. A suitableclamp is provided for holdingl the gage in any of its adjustedpositions,

said clamp consisting, for instance, ofV a' thumb-nut c', fitting a bolto8, which passes through a lug c2 on the side of the ,gage C and throughthe slot x2, the head of the bolt (not shown) taking under the sides ofthe slot m2 on the under side of the bed.

A laterally-projecting lip D is provided at the top of the gage C. Theobject of this lip is to prevent a strip of rule that is being miteredfrom being tipped up by the force of the mitering operation, which is asfollows: The

Theface b of this angle of initer is determined by the angle at whichthe gage C is set. The strip of rule to be mitered is placed on edgewith its fiat side resting against the gage C, and being held there byone hand of the operator, the top edge of the rule fitting under lip D.The lever A is slightly elevated and the rule pushed along until its endat the upper corner rests against the lug B. The lever then is depressedand the cutting-edge a2 shaves off the metal. The lever is raised andagain lowered and the operation repeated until the desired amount ofcutting is produced. The lever is only raised sufficiently each time sothat the upper corner of the rule end will abut against the lug B, thebeveled face h of which serves to bear off the knife from the rule,preventing too heavy a cut. The brace Eis supported and held by a heavybolt Gl a short distance from the straight edge of the arcbed,sufficient to allow the lever to drop between the brace and said edge.This brace,

at the other end from the bolt Gr, is supported IOO by one end of thefulcruxn-pin F, the other end of the pin being supported by the bearing094. This brace serves as a strong binding connection for thefulcrurn-pin, which thereby bears great straining-power when cuttingheavy rules. The arch between the cuttingedges a and CL2 rests upon thebolt G, which thus serves as a stop for the lever when it is forceddown.

When it is desired to cut a rule to a given length, the rule is laid onthe rule-bed and the knife a cuts oit the end, the length or l distanceof the cut from the end being determined by the end of the rule beforecutting being placed against the gage H, which is carried at the end ofa screw-threaded rod J, said rod passing into a tapped hole in the base,thereby giving a tine screw adjustment in moving the gage H in and out.We also secure a second screw adjustment by use of a small screw hpassing through the gage H, against which the rule may abut.

Having now described our invention, what we claim, and desire to secureby Letters Patent, is- Y p l. In a rule-lnitering machine, a base havinga lever pivoted thereto, said lever being provided with a cutting-edgeon one side parallel with the longitudinal axis thereof, and a lugextending under the lever nearly to the vertical plane of thecutting-edge, said lug having a beveled face, substantially asdescribed.

2. In a rule-mitering machine, a base having'a lever pivoted thereto anda swinging rule-gage, said lever being provided with a cutting-edge onone side parallel with the longitudinal axis thereof, and a lugextending under the lever and having a beveled face, substantially asdescribed.

3. In a rule cutting and mitering machine, the combination, with a basehaving a rulebed and a swinging rule-gage, of a lever pivoted to saidbase and having two cuttingedges opposite the ends of the said bed andgage, substantially as described.

t. In a rule-cutting machine, the combination, with a base having acutting-lever pivoted thereto, ofthe brace E, connecting the end of thelever-fulcrum with a portion of the base distant from said fnlcrum, saidbrace being parallel to the lever when down, substantially as described.

5. In a rule-cutting machine, the combination, with the base, of thegage H, having a screw-threaded rod J, entering a tapped hole in thebase, and the screw h, passing through gage H, substantially asdescribed.

In testimony whereof We affix our signatures in presence of twosubscribing witnesses.
